FLAKE
GRAPHITE / GREY IRONS
The Metallurgy of MEEHANITE Flake (Grey/Lamellar)
Iron
In the production of Meehanite flake graphite castings, the
composition of the iron, whilst important, is only a part of
the process for achieving a definite metal structure. The more
important factor is mass, ie wall section thickness, and its
effect on cooling rates. For normal cast iron, slow cooling
(as in thick sections) produces a coarse open-grained, low strength
structure, whereas fast cooling (as in thin sections) results
in a hard, brittle, unmachinable structure. Thus in Meehanite
practice, the structure of the metal and properties required
are related to the section thickness of the casting.
